HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 511, 955 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 511, 955 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 511, 955 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 511, 955 is 1.
HCF(511, 955) = 1
HCF of 511, 955 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 511, 955 is 1.
Highest Common Factor of 511,955 is 1
Step 1: Since 955 > 511, we apply the division lemma to 955 and 511, to get
955 = 511 x 1 + 444
Step 2: Since the reminder 511 ≠ 0, we apply division lemma to 444 and 511, to get
511 = 444 x 1 + 67
Step 3: We consider the new divisor 444 and the new remainder 67, and apply the division lemma to get
444 = 67 x 6 + 42
We consider the new divisor 67 and the new remainder 42,and apply the division lemma to get
67 = 42 x 1 + 25
We consider the new divisor 42 and the new remainder 25,and apply the division lemma to get
42 = 25 x 1 + 17
We consider the new divisor 25 and the new remainder 17,and apply the division lemma to get
25 = 17 x 1 + 8
We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get
17 = 8 x 2 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 511 and 955 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(25,17) = HCF(42,25) = HCF(67,42) = HCF(444,67) = HCF(511,444) = HCF(955,511) .
